Image tools / practical guide
Add text or a logo to a batch of images with position, opacity and size controls.
A practical starting example
Make a mark readable without hiding the subject
Use a copy of a product photo, choose a corner and inspect the mark at the image’s real display size. A mark that is readable on a large photo can overpower a small one. Check position and opacity across a mixed-size batch before exporting.
Use this as a small trial before applying the operation to your real input. A sample illustrates the workflow; it does not promise a specific result for every source file or device.
How to use Image Watermark
- Prepare a copy of the input. Supported inputs: JPG, PNG, WebP.
- Choose the operation and review the controls below before running the sample.
- Run the tool, then inspect the new output before using it.
Prepare the input
Use the controls described in the application. Supported inputs: JPG, PNG, WebP.
Supported input and output scope: JPG, PNG, WebP
Review the available controls
Choose text or a logo, then adjust position, opacity and mark size. Text mode also offers text and colour controls. Logo mode requires a logo image. Inspect both portrait and landscape outputs before applying the same settings to a batch.
How to decide whether the result is useful
Choose a corner and check the preview at full size. Text or logo dimensions are calculated relative to each image width.
- Compare the output with the unchanged source.
- Check the destination requirement before copying, downloading or uploading it.
- Open the downloaded file in the receiving application and check its actual type, size and contents.
- Use a second representative sample if the first does not cover the difficult part of your input.
Limitations and troubleshooting
Watermarks alter the output pixels. The original selected files stay unchanged; very small images may need a smaller mark.
If the output does not match your intention
Return to the original copy, review the selected input and controls, and repeat with a smaller sample. If the embedded view is unavailable, use the direct tool link at the top of this page. Browser support and device memory can affect file-based workflows.
Questions about this tool
What should I check first?
Choose a corner and check the preview at full size. Text or logo dimensions are calculated relative to each image width.
Can I use the tool from this guide?
The main button opens the working tool on its Tabaix subdomain. An optional embedded view may be added to this guide; the direct link remains available for larger screens, downloads or browser compatibility.
What should I keep before changing the input?
Keep an unchanged source and record any controls you chose. That gives you a comparison point and lets you repeat the task without replacing your original.
